Notable WebGPU CTS changes:
- Demotions from tier 2 to tier 3:
- `webgpu:shader,execution,expression,unary,{i32,u32}_conversion:f32:*` started regressing on Windows.
- Promotions to tier 2 from tier 3:
- Across all platforms:
- `webgpu:shader,execution,expression,call,builtin,cross:f32:*`
- `webgpu:shader,execution,expression,unary,i32_conversion:abstract_float:*`
- `webgpu:shader,execution,expression,unary,u32_conversion:abstract_float:*`
- `webgpu:shader,execution,limits:nesting_depth_braces:*`
- `webgpu:shader,validation,expression,call,builtin,value_constructor:vector_copy:*`
- `webgpu:shader,validation,expression,call,builtin,value_constructor:vector_elementwise:*`
- `webgpu:shader,validation,expression,call,builtin,value_constructor:vector_mixed:*`
- `webgpu:shader,validation,expression,call,builtin,value_constructor:scalar_zero_value:*` was promoted on Linux and Windows, but stays in macOS on account of failing `f16` functionality. My guess is that these failures are also present on the other platforms, but we don't see the because `shader-f16` is not aviailable on our other CI platforms yet.
- From macOS, completing the set of all platforms passing:
- `f16` functionality, which, again, was likely not visible on our other CI platforms before:
- `webgpu:shader,execution,expression,call,builtin,cross:f16:*`
- `webgpu:shader,validation,decl,override:type:*`
- `webgpu:api,validation,capability_checks,limits,maxUniformBufferBindingSize:createBindGroup,at_over:*`
was promoted on Windows.
